First-aid measures Inhalation If breathing is difficult, remove to fresh air and keep at rest in a position comfortable for breathing. Call a physician if symptoms develop or persist. Skin contact Take off immediately all contaminated clothing. Rinse skin with water/shower. Call a physician or poison control center immediately. Chemical burns must be treated by a physician. Wash contaminated clothing before reuse. Eye contact Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Call a physician or poison control center immediately. Ingestion Call a physician or poison control center immediately. Rinse mouth. Do not induce vomiting. If vomiting occurs, keep head low so that stomach content doesn't get into the lungs. Most important Burning pain and severe corrosive skin damage. Causes serious eye damage. Symptoms may symptoms/effects, acute and include stinging, tearing, redness, swelling, and blurred vision. Permanent eye damage including delayed blindness could result. Indication of immediate Provide general supportive measures and treat symptomatically. Chemical burns: Flush with water medical attention and special immediately. While flushing, remove clothes which do not adhere to affected area. Call an treatment needed ambulance. Continue flushing during transport to hospital. Keep victim under observation. Symptoms may be delayed. General information Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. 5. Fire-fighting measures Suitable extinguishing media Water fog. Foam. Dry chemical powder. Carbon dioxide (CO2). Unsuitable extinguishing Do not use water jet as an extinguisher, as this will spread the fire. media Specific hazards arising from During fire, gases hazardous to health may be formed. the chemical Special protective equipment Self-contained breathing apparatus and full protective clothing must be worn in case of fire. and precautions for firefighters Fire fighting Move containers from fire area if you can do so without risk. equipment/instructions Specific methods Use standard firefighting procedures and consider the hazards of other involved materials. General fire hazards No unusual fire or explosion hazards noted. 6. Accidental release measures Personal precautions, Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Wear protective equipment and appropriate protective equipment and clothing during clean-up. Do not breathe mist or vapor. Do emergency procedures not touch damaged containers or spilled material unless wearing appropriate protective clothing. Ensure adequate ventilation. Local authorities should be advised if significant spillages cannot be contained. For personal protection, see section 8 of the SDS. Methods and materials for Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is containment and cleaning up possible. Absorb in vermiculite, dry sand or earth and place into containers. Prevent entry into waterways, sewer, basements or confined areas. Following product recovery, flush area with water . Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to remove residual contamination. For waste disposal, see section 13 of the SDS.

Never return spills to original containers for re-use. Environmental precautions Avoid discharge into drains, water courses or onto the ground. 7. Handling and storage Precautions for safe handling Do not breathe mist or vapor. Do not get in eyes, on skin, or on clothing. Provide adequate ventilation. Wear appropriate personal protective equipment. Observe good industrial hygiene practices. Use care in handling/storage. Avoid prolonged exposure. Conditions for safe storage, Store locked up. Store in original tightly closed container. Store away from incompatible materials including any incompatibilities (see Section 10 of the SDS).
